The Rapid Development of 4G Technologies
Due to the growing need to carry out more and more tasks on the internet with mobile phones, the technology has been improving since the first generation of analog 1G phones during the 1980s and the 2G with the arrival of digital telephony, up to get to the current 4G technology. But what is 4G? And what is the difference between 4G and 4G LTE?
In simple and conventional terms the 4G is only the fourth generation of wireless mobile telecommunication technology which makes it the natural successor of 3G, and thanks to its high download speed it becomes, theoretically, at the ideal speed level for services such as high-definition video calls, live streaming, geo-location and the ability to play online. With the 4G the user receives reliable and high-speed Internet connectivity in different electronic devices, such as tablets and smartphones, among others.
Although the fact that it is faster than 3G does not immediately convert it to 4G. When it was decided to use the 4G nomenclatures, the International Telecommunication – Radio communication Union (ITU-R) introduced a series of technical requirements for a network to be called 4G. One of the characteristics that the 4G network should have is that a connected device, for example, a smartphone, could access a speed of 1 Gigabit per second (Gbps) when the user is moving at low speed and 100 Mbps, while the user moves faster.
However, the ITU-R realized that it had set difficult goals to reach and soon realized that the bar had set too high. Despite this, the ITU-R allowed the commercialization of the 4G name as companies use more advanced technology and improvements in Internet speed are presented.
Long Term Evolution (Long Term Evolution or LTE by its name and acronym in English) is a standard for high-speed wireless communication. LTE networks offer lower speeds than a true 4G network can offer.
It began to be used commercially after the ITU-R realized that the minimum speeds established for the 4G networks were far from the service providers’ reach, so the marketing of the 4G LTE name began with the permission of the authority of a regulator. An opportunity that mobile phone companies did not waste, especially in developing countries, effectively attracting customers with the much venerated term ‘4G’ attached to the LTE.
The problem now is the coverage and infrastructure that is required in different countries to be able to use this network in compatible mobile phones, since not all devices are compatible, nor all SIM cards.
It is expected that the next generation of internet speed technology will be called 5G, while some of the technological giants are already working on it, it is hoped that the technology can be ready soon.
